How We Work
How We Work At 121 Dietitian, we understand that we all have the best intentions when it comes to our nutrition and health. However, committing to lasting change can require specialist support. This page explains how we work with you to create practical, personalised and sustainable health improvements. The support and advice at 121 Dietitian is not only for those with weight concerns, but also for individuals struggling with long-term health conditions. This reflects how we work – taking a comprehensive and personalised approach to your health. For example, this may include unexplained fatigue, IBS, low mood, gastrointestinal or inflammatory issues, diabetes, cancer, heart health concerns, hormonal imbalances, thyroid conditions, or sports performance challenges. Most people hear the term “Dietitian” and immediately think of weight loss and lettuce leaves… boring! However, we are delighted to let you know that at 121 Dietitian, we are fun, friendly experts in nutrition and its vital role in medicine and overall health. Importantly, we stay at the forefront of new knowledge and research, continually developing our skills. In particular, one area of focus is nutrigenomics. As a result, you will receive the most up-to-date, evidence-based, and bespoke advice tailored specifically to you. Do You Need A Dietitian Referral? Did you know you can book to see a Dietitian without a referral from your GP or consultant? This is especially important because many patients face long waiting lists. Moreover, private scans and scopes can be costly and may not be necessary at this stage – or indeed at all. This approach forms an important part of how we work, ensuring you receive timely and appropriate care without unnecessary delays. Many of the patients we see have already paid for expensive tests, yet they receive no clear diagnosis. While it is reassuring to know nothing sinister requires treatment, this often does not resolve the ongoing symptoms. In fact, most people have a functional digestive issue that can be treated effectively through diet. If we assess you and believe you need medical intervention, then we will direct you to the right specialist for appropriate tests. If none of the above applies to you, then you may fall into the “Check Up and Change” camp. In this case, you do not have an existing health problem; instead, you may simply want a ‘Diet MOT’ or diet assessment for peace of mind, so that you can feel confident in your long-term health choices. After all, prevention is better than cure. Whatever your reason for having your diet assessed, we can help. Alternatively, why not consider a loved one or friend? Simply, contact us to arrange a gift voucher. How We Work In A ‘Nutshell’ At 121 Dietitian, this is how we work: we translate evidence-based medical advice into easy-to-follow, detailed, tailor-made dietary programmes, so that you can implement clear and practical changes. Our package options outline the fees you can expect to pay for a standard dietary concern. However, additional dietary or medical issues may require further input. Therefore, prices may vary to reflect the time and expertise required to ensure your programme is fully specific to you. How We Work In Northern Ireland This is the only private dietetic service of its kind in Northern Ireland, due to the level of detail we analyse and the depth of advice we provide. Importantly, we treat the whole person – not just individual symptoms – through our specialist programmes. As a result, this whole-person focus reflects how we work in practice — with depth, detail and genuine care. We run our main clinic in Holywood, Co Down. However, we also offer worldwide online consultations, so you can access expert support wherever you are. If you are ready to begin, then you can book today using our client portal, Practice Better. Alternatively, you can take a tour to see exactly how our portal looks and how it works.

Fathers day – more food!
The Fathers Day weekend is almost over. In our house it has been made extra special by the hot sunny weather. We have enjoyed eating alfresco, breakfast, lunch and supper; with the humour of being on holidays and ‘when’s the flight home’? Now for many today, like ourselves, we were caught up in Fathers Day. Our 3 kids were up early scurrying around putting finishing touches to the envelopes off cards and gifts! Hubby lay on in bed for the honorary grapefruit, but I drew the line at croissants, these were to stay firmly in the kitchen area! I hate crumbs especially in bed, yuk! After breakfast came what seem like minutes later, snack time. Huh I had just cleared the breakfast. Out came the bits and pieces again and the noise of chewing and slurping was priceless; apple, strawberries and blueberries. Off we went on a cycle our first long bike trip, 9 miles in total. Obviously interrupted by a packed ‘picnic’ just in case our blood sugars should drop ever so slightly! This was light as I was carrying the bag! Bananas, oatcakes, World Cup crisps and water. Home and you guessed it, before I could walk to the fridge the chorus off, “I’m hungry” rang out. Lucky I was fully prepared and out came a rainbow off colours to be piled up high and rolled into wraps. King prawns, homemade guacamole, salad, tomatoes, peppers, etc…. 2 wraps each later and large eyes were still able for the home-made Victoria sponge cake! Friends and family often comment on the fact that my kids appear bottomless pits. Now my food bill makes me think I am harvesting a family of tapeworms! Luckily lunch did the trick, and eggy bread was all they could manage before rolling into bed! Information checked & correct on 16th May 2018.
Belfast dietitian – A New Week..
Work, shop and clean seems to be the routine I tackle daily, cooking however is creative, uplifting and relaxing, only if all afore mentioned tasks are in place! Today, no matter how hard I tried not to, I had to tackle the house mess from the weekend. 3 mad ‘arts and crafts’ nuts live in my house and the mess seems to pile up as quickly as I am throwing it out for recycling! Not alone this mess, the amount of crumbs trailed around was enough to beat the loaves and fishes story, you know the one! Now all are in bed filled with tryptophan rich foods for a long and peaceful nights sleep! Lucky, my friends say, when I report my kids eat anything, and yes this is true, but it did take time, energy and frustration from the beginning to create those well tuned palates they all possess today. Tonight we had a lovely homemade fish pie, to make it more healthy and tasty instead off adding fats like butters and cheese, I added 2 tablespoons of pesto to the sauce, try it, it is yum! For dessert yoghurt in any shape or form is welcome, freeze it, mix flavours and plain, its so versatile! Now off to think off what to get for packed lunches tomorrow. I just don’t want any more mess to clean! If you are unsure of how to change your eating habits, or need help optimising the foods you eat please do contact us. We would love to help you or your family and friends with any nutrition related queries big or small.
